The method of observing and measuring lever and spleen of mice by using type B ultrasonic detector.

Objective:To inquire the possibility of measuring lever and spleen of mice with ultrasonic detector and offer some relevant reference data.Methods:Thirty mice were fixed on their back and their lever and spleen were observed and measured with high-frequency ultrasonic detector.Results:The lever and spleen of mice could be clearly observed and easily measured under ultrasonic detector.The oblique axis of right-leaf lever is(1.50±0.07)cm,and the length and thickness of left-leaf lever were(1.53±0.07)and(0.54±0.04)cm,respectively.The average diameter of portal vein was(0.11±0.01)cm.The thickness and length of spleen were(0.46±0.06)and(1.45±0.06)cm,respectively.Conclusion:It was a new,available and harmless method for observing and measuring lever and spleen of mice with ultrasonic detector.
